Pulmonary Disease, Chronic Obstructive
Does Severity of Airflow Obstruction Correlate to Static Lung Volumes
Obstructive lung disease is defined by limitations in expiratory airflow, caused by excess mucus, loss of muscle tone, and structural changes. Over time airflow reduction can lead to gas trapping in the lungs (hyperinflation).

Complexity of the Airflow in COPD
Recently, there has been a growing interest in the study of nonlinear dynamics as a methodology for complementary analysis to characterize the respiratory pattern. These methods are well established in studies of heart rate.
